APPLICATIONS

With the­se back-up rings the ope­ra­tio­nal ran­ge of pre­cisi­on O‑rings extends to a maxi­mum ope­ra­ting pres­su­re of 1,000 MPa.

SHR series
HP high pres­su­re back-up ring

  • For sta­tic app­li­ca­ti­ons and line­ar moti­on
  • Advan­ta­ges of the con­ca­ve form as for the SKS and SKC series
  • Requi­red for lar­ge groo­ve depth varia­ti­ons and gap expan­si­on cau­sed by pres­su­re breat­hing
  • For instal­la­ti­on in split groo­ves only

SHA series
HP high pres­su­re back-up ring, exter­nal instal­la­ti­on

  • For sta­tic app­li­ca­ti­ons, inter­nal pres­su­re
  • Advan­ta­ges of the con­ca­ve form as for SKA series
  • Requi­red for wide groo­ve depth varia­ti­ons cau­sed by pres­su­re breat­hing
  • Easy to install in non-split groo­ves

SHI series
HP high pres­su­re back-up ring, inter­nal instal­la­ti­on

  • For sta­tic app­li­ca­ti­ons, exter­nal pres­su­re
  • Advan­ta­ges of the con­ca­ve form as for the SKI series
  • Requi­red for lar­ge groo­ve depth varia­ti­ons cau­sed by pres­su­re breat­hing
  • Easy to install in non-split groo­ves

CHARACTERISTICS

Sys­tem advan­ta­ges:

  • Pro­duc­tion costs can be redu­ced due to lar­ger clearan­ce gap 
  • Pre­vents metal con­tact 
  • Com­pen­sa­tes clearan­ce gap and cross-sec­tion varia­ti­ons cau­sed by pres­su­re expan­si­on, ther­mal expan­si­on, play and dis­pla­ce­ment
  • Allows the use of pre­cisi­on O‑rings of medi­um hard­ness 
  • Sui­ta­ble for almost all fluids 
  • Avail­ab­le for any cross-sec­tion dia­me­ter and for indi­vi­du­al groo­ve dimen­si­ons 
  • Easy to install
  • Inex­pen­si­ve com­po­nent with a mas­si­ve effect

TEMPERATURE RANGE

From ‑200 to +200 °C

but depen­dent on the back-up ring mate­ri­al in each case.
